Research

Interests = information theory; coding theory; polar code; distributed system; application of algebra and combinatorics.

For meta-comments of my works categorized by topics, see:

I have once computed, on a supercomputer, the Tutte–Whitney polynomials of Reed–Muller codes of length 64. This GitHub repository keeps the source codes, comments, and results.

TikZ TeX Talk collects some of my ideas for (La)TeX and TikZ.

Vaseman is about drawing people that look like vases. (Data plan warning: scans of drawings!)

Oriclip is about binder clip sculptures. (Data plan warning: a lot of photos!)
